Algerian mail used stamps of
France beginning 1 January 1849. Early
cancellations were a simple grill similar to French usage, but after
1852 the service switched to a lozenge of dots surrounding a number
identifying the post office.
Beginning in 1924, French stamps were overprinted "ALGÉRIE", eventually
to total some 32 types over the next couple years. These were
superseded in 1926 by the first stamps inscribed for Algeria, the
series consisting of four typographed designs showing local scenes, and
ultimately consisting of 35 types, ranging from 1 centime to 20 francs.

Official stamps of Algeria related to Paleontology: fossils

[2] Archeologists have discovered
lithic tools and animal bones on the site of
Ain Al Hanesh dating from 2.4 million years ago. The French
paleontologist Camile Arambourg was able to prove the existence of a
plio-pleistocene deposit, in addition to his classification of these
fossilized bones (elephants, equids, cows, hippopotamus, rhinos, etc.),
as well as cut pebbles constituting Oldowan sub-spheroidal and spheroidal
polyhedrons that makes this discovery the first of its kind regarding
very old archeological remains found next to fossilized bones of savanna
animals.
